This is a Uniqlo linen blend long shirt. It's a size S, but the width is very roomy, so I think even those who usually wear M can wear it comfortably. I was able to wear it during my pregnancy. It's an oversized shirt with slits, allowing the wind to pass through, making it cool and recommended for hot days. There are pockets on both sides. Worn for only one season. I am also selling a white version in a different color. - Color: Khaki - Style: Shirt dress - Sleeve length: Short sleeves, which look like French sleeves when worn. - Collar design: Shirt collar - Back design: Tucked Thank you for looking.
